BlueOptics singlemode LC/APC simplex optický atenuátor 25dB

The BlueOptics SFA21BM25 is a high-quality fiber optic attenuator designed for singlemode networks. It provides precise 25 dB attenuation with LC/APC connectors in a simplex configuration, ensuring reliable signal reduction in telecommunications, data centers, FTTx, CATV, and LAN applications.

Advantages

This attenuator offers excellent return loss (>60 dB) and low additional insertion loss (<0.2 dB), maintaining signal integrity. Its zirconia ceramic ferrule ensures durability over 500 mating cycles, and the angled physical contact (APC) polish minimizes back reflections. The green color code indicates APC polish for easy identification.
